* The u-boot networking stack is a little weird. It seems like the
* networking core allocates receive buffers up front without any
* regard to the hardware that's supposed to actually receive those
* packets.
*
* The MACB receives packets into 128-byte receive buffers, so the
* buffers allocated by the core isn't very practical to use. We'll
* allocate our own, but we need one such buffer in case a packet
* wraps around the DMA ring so that we have to copy it.
*
* Therefore, define CFG_RX_ETH_BUFFER to 1 in the board-specific
* configuration header. This way, the core allocates one RX buffer
* and one TX buffer, each of which can hold a ethernet packet of
* maximum size.
*
* For some reason, the networking core unconditionally specifies a
* 32-byte packet "alignment" (which really should be called
* "padding"). MACB shouldn't need that, but we'll refrain from any
* core modifications here...
